Sony doesn't have employees in its R&D division. It has wizards. And those wizards are working on all kinds of 3D tech. Such as?

In an interview with Develop, Sony's Mick Hocking runs through what Sony is working on beyond 3D on televisions. Sure, many companies are working on 3D for portable devices, Hocking concedes, and Sony is, too.

"We also have techniques like holographics for the PS3 that I think will be very interesting for the future 3D games," he adds. But that's not all Sony is creating.

"In regards to that we have some new technology that we've shown to developers that uses 3D techniques, it allows two players to play full screen multiplayer games but without each being able to see the others view, and they have been massively keen on them," he continues. "There's lots to come." Can't wait!

But, as website Games Radar points out, don't expect a PS3 branded volumetric display device just yet. Instead, this sounds like Sony's 3D alternative to split-screen multiplayer. Ideally, this would allow both players the view of an entire screen, without either the distraction of their opponent's activity to the side, or the ability to cheat by looking at his screen to see where he is.
